SPECIFICATION forming part of Letters Patent No. 738,673, dated September 8, 1903.

`.'lpplicatolriiled November 7, 1902. Serial No. 130,434. (No model.)

1 To all whom it may concern:

Be it known that I, FREDERIC GRAEF, a citizen of `the French Republic, residing fat 203 Rue Lafayette, Paris, France, have invented certain neT and useful Improvements in- Vehigous accident.l

lVith thisobj ectin view the invention cone sists in the improved construction, arrangement, and combination of the parts of vehicleshafts hereinafter fully described and afterward specifically I claimed.

In the accompanying drawings, which illustrate my invention, Figure l is a view, partly in elevation and partly inlongitudin alsection of parts of the two sections of a shaft separated from each other. Fig. 2 is a similar View, the section being on a plane at a right angle to that ofFig. l; Fig. 3 is a view of small portions of the two sections of the shaft joined together. Fig. 4 shows, respectively, on the left and right end elevations of the rear and front sections of the shaft.

Like letters of reference mark the same parts in all of the figures.

Referring to the drawings by letters, ci and b indicate the rear and front sections of a shaft, respectively. In abore in the end of the section a is inserted a socket c, in which are mounted two latch-springs d and e, adapted to receive when the'sections CZ and e are pressed together the arrow headed pin f,

which projects from a plate g, secured by screws or otherwise in the end of the section b.

Bythis means the two sections a and b Willbe held together during all ordinary uses, but will come apart when extra strain is brought upon the joints. In order to prevent any twisting movement of the joint, dowel-pins h and c', projecting from the end of the section a, engage in holes in the plate g, as shown in Fig.` 2. The pressure of the animal in falling will tend to separate the sections a and b,

thus reducing the liability of breakage.

It is obvious that each shaft may be made in as many such jointed sections as is found desirable.

Having thus fully described my invention,

`'what I claim as new, and desire to secure by Letters Patent of the United States, is

A vehicle shaft comprising a plurality of sections joined end to end, a socket in the `meeting end of one section, latch springs
